Video is a specialised topic, where as this is an excellent but general forum.
If you are new to Video, then I feel i should point out that Studio 8 does not run smoothly on all machines. You could do worse than try some trial versions of other editing software. Making sure you uninstall each before placing another on your machine. To uninstall Studio fully, however, you will need to visit the Pinnacle site and get yourself a copy of there "uninstaller". Which beggers the question, what kind of software is it?
Good luck and have fun.
